MACHINE FOR AFFIXING LABELS on THE LIKE.

Application filed .luly a, 1924. Serial No. 723,978.

known to provide the adjacent endsof two swinging levers with adhesive faces, which grip the lowermost label of the pile at two opposite edges and lead it to the'object to be labelled. Such known apparatus is used for labelling bottles-Where it is sufiicient for the ends only of the labels to'be coated with adhesive. 1

As distinguished from this in accordance with the present invention the whole surface of the label is carefully coated with adhesive in order that the label can be applied to a box and will serve as a closing or sealing medium. For this purpose the rocking levers are so arranged that their ends abut and form a substantially continuous adhesive coated face of the size of the labels. The pile is lowered on this face after the face has been coated with adhesive by means of a roller similar to the roller employed in the inking of printing plates. The lowermost label adheres to the adhesive coated face. It is held against the one lever by means of a clamping bar or the like. Vhen the levers are subsequentlymove'd a part of the label is withdrawn from the face of the one lever and the adhesive is thus well distributed thereover. The leverholding the label is then moved further till the free edge of the label comes in contact wit the box or the like which has been moved in position during this operation. The

label is then gripped by a roller, which is led over the box face to be gummed, andis thus rolled down on the face, the second part of the label being then withdrawnfrom its lever, so that the adhesive on this portion is'also well distributed.

is a detail view. of a partofthe F igsBto 6 are diagrammatic illustrations to enlarged scale affording an explanation of the modus operandi. of the machine.

As shown, the strips are piled in an upright cage 1 loaded by a weight 2 in the usual manner. The cage is secured to an I-shaped member 3 slidable in guides 4. To, 7 I

the pivots 5 mounted on the member .3 is connected by links 6, a lever 8 ,pivote'd at 7. This lever carries a-roller '9 whichwith a cam. disc 10 engages with a continually rotating shaft 11. This cam disc lOfthus, produces a vertically reciprocating motion of the cage 1 containingthe pile of strips,

At a short distance beneaththe pile of strips-is arranged a horizontal surface formed of the two parts 12 and 18 (Fig.3) These surfaces are formed by the ends of abutting rocking levers 14 and'15 which each form 'onearm of afbell crank lever 16 and 17 (Fig. 1), which swing about the pivots 18 and 11 and are provided at their vfree ends with rollers. 19 and 20.. I

These rollers bear on'c'am discs 21 and 22, springs being provided if necessary tojensure contact, whichcam discs 21and 22 are secured to. continuously. rotating shafts p 23 and 24. The-cam discs 21 and 22 ensure that the lever arms 14 and '15 will beheld in the position shown in thin lines in Fig. 1 during the major portion of the rotation of the shafts 28'and24, in which the lever ends 14 and 15 abut and thus the two parts 12 and 13 form a connected surface (Figs. 3 and 4). Only when the cams on the discs 21and 22 contact with the rollers 19 and 20 are the lever arms 14 and 15 brought.

downwards into the separated position shown in Fig. I .1

On the machine arm A is provided an adhesive container 25 into which dips a roller 26 mounted on acontinuously rotating,v

shaft 27. The roller takes up adhesive and applies it in known manner to asecond roller 28 contacting therewith. A third roller 29 comes intermittentlyfinto contact with the roller 28 so that the adhesive is applied to the periphery of this roller in a well distributed condition. The ro1ler29 is pivotally mounted on a horizontal support .30 against the oppositeend of which bears-a cam disc'-'31;secured to the shaft 11. I f
